Exception in client function causes function host to restart.

See original GitHub issue

As a Function Developer In order to monitor failures I need to exit a function with different exit codes and to control whether a failing message is retried or dead-lettered

Expected behavior

Temporary Failure

Given V.2 Service Bus Trigger
When the client function throws an temporary execution error
Then the message should be retried

Permanent Failure

Given V.2 Service Bus Trigger
When the client function throws an permanent execution error
Then the message should be dead-lettered

Actual behavior

Given V.2 Service Bus Trigger
When the client function throws any exception
Then the function host is restarted
And the telemetry is not sent to AppInsights

as your unwillingness to improve the product

I’m sorry if you’re getting this impression, but that is absolutely not the case. We have looked at your reports and followed up on them; we do need your help with repros where requested as we’re unable to validate the behavior you’re reporting. Can you please provide some help with that?

@fabiocav @mathewc - Also please re-open both #2085 #2086 #2087 as your unwillingness to improve the product reflects extremely badly on the dependability AzureFunctions as a platform.
